About LED Lighting



The field lumens on the cut sheets for the Bear line of LED fixtures are based on the actual field measurements of foot*candle readings. It has to do with photopic and scotopic light readings. When the photopic lumens that are measured in the lab are used to do photometrics for a project, the results will always show less light output then is measured after the actual install. So the lumens on the Bear fixtures cut sheets are field effect lumens based on testing and the results of many installs.

The human eye sees 1.84 times more light from full-spectrum LED source than conventional fixtures. Conversely, less light is needed to achieve same visual recognition.

PowerCatch Inc. is an approved Dealer for industrial, architectural, and commercial grade LED lights, these fixtures can be used in facilities such as parking garages, parking lots, gas station canopy fixtures, gymnasiums, wall packs and high bay LED warehouse lights.

Reasons why you should use Power Catch’s LED lighting:

Huge Energy Savings

Power Catch carries several product lines- our Bear LED Heavy Duty Industrial Series has the coolest running industrial LED fixtures on the market, 1-3 Degrees Celsius over ambient temperature because they run cooler they use less power. LED chips emit light after wired with power. About 75% of the electric power is turned into heat energy. In LED fixtures commonly used today, this heat energy is trapped in the fixture itself, limiting the LED’s performance and lifespan. Our patented LED heat dispenser technology moves the heat energy away from the LEDs, providing extended longevity and lumen output.

Our Architectural Modular Series are aesthetically pleasing and are modular. Power Catch can increase lumen by adding more LED bars. In addition, the same fixture head can be used as a street light, gas canopy light, wall pack, parking light, and tunnel light, which provides our clients with the same design throughout. Less power consumption equates to lower operating costs and a quicker return on your investment. Often we see energy savings in the 80% to 90% range, saving thousands of dollars each month.

See “Defining LED Useful Life”


SSL – solid-state lighting; umbrella term for semiconductors used to convert electricity into light.
LED – light-emitting diode.
CCT – correlated color temperature; a measure of the appearance of a white light source. CCT is measured on the Kelvin absolute temperature scale. White lighting products are most commonly available from 2700K (warm white) to 5000K (cool white).
CRI – color rendering index; a measure of how a light source renders colors, compared to a “perfect” reference light source. CRI is given as a number from 0 to 100, with 100 being equivalent to the reference source.
Lumen Maintenance – the percentage of initial light output produced by a light source at some percentage of rated useful life (usually 100% for LED and 40% for source types characterized by sudden failure).

Junction Temperature

Junction Temperature is the temperature at the point where an individual diode connects to its base. Maintaining a low Junction Temperature increases output and slows LED lumen depreciation. Junction Temperature is a key metric for evaluating an LED product’s quality and ability to deliver long life.

The three things affecting Junction Temperature are: drive current, thermal path and ambient temperature. In general, the higher the drive current, the greater the heat generated at the die. Heat must be moved away from the die in order to maintain expected light output, life and color. The amount of heat that can be removed depends upon the ambient temperature and the design of the thermal path from the die to surrounding. (Source: Department of Energy)

The Department of Energy advises: “Heat management and an awareness of the operating environment are critical consideration to the design and application of LED luminaries for general illumination. Successful product will use a superior heat sink design to dissipate heat and minimize Junction Temperature. Keeping the Junction Temperature as low as possible and within the manufacturer specifications is necessary in order to minimize the performance potential of LEDs.”

High Quality Lighting

The CRI measures the ability of light sources to render colors, compared to incandescent and daylight reference sources. The CRI has been found to be an unreliable predictor of color preference of LED lighting products. A new metric called the Color Quality Scale (CQS) is under development, but in the meantime, color rendering of LED products should be evaluated in person and in the intended application if possible. Depending on the application, many of our LED characteristics have the following:

  • Directional Light
  • Low profile / compact size
  • Breakage and vibration resistance
  • Improved performance in cold temperatures
  • Life unaffected by rapid cycling
  • Instant on / no warm up time
  • No IR or UV emissions

Extended Fixture Life

Our Industrial Series LED fixtures are very durable and essentially unbreakable. According to Energy Star requirements for LED estimated life span, light saving rate is 99.08% for 6,000 hours. Our measured, light saving rate is 98.00% for light fixture in 6,000 hours. Our warranty guarantees that no less than 93% of diodes are operational for five (5) years and we do not mandate any outdoor fixtures be on a photo cell. Our fixtures are getting 122 field lumens / watts through magnifying lenses on the LED. When retention rate is less than 70%, the Department of Energy regards it as LED failure. Failure time for our Bear industrial fixtures and our Lion commerical series are beyond 100,000 hours.

How Long Do LEDs Last?

Unlike other light sources, LEDs usually don’t suddenly “burn out”, instead they gradually fade in brightness over time. LED useful life is generally based on the number of operating hours until the LED is emitting 70% of its initial light output. Good quality LEDs in well-designed fixtures are expected to have a rated useful life on the order of 50,000 to 100,000 hours. A typical incandescent lamp lasts about 1,000 hours, a comparable CFL lasts 8,000 to 10,000 hours, and some linear fluorescent lamp-ballast system can last more than 40,000 hours. LED output and useful life are strongly affected by temperature. LEDs must be “heat sinked” (placed in direct contact with materials that can conduct heat away from the LED) and driven at an appropriate input current.

Best of the Best

Our LED light fixtures use only the best components from leading manufacturers. Cree, Osram and Inventronics are international corporations that build the key components of our LED Lighting. These corporations are providing financial depth and security for the best warranties offered on the market. Each Industrial Series light carries a 10 year warranty on the coatings, housings, drivers and the light emitting diodes. Our fixture’s useful life is over 100,000 hours.

Good For Our Planet

Reduce your energy consumption while removing hazardous materials from the work place and consumer environment. Replace conventional glass filament and fluorescent bulbs with LED fixtures that do not shatter and do not contain contaminants, protecting your staff and customers.

100% Recyclable

All LED fixtures are 100% recyclable and contain no hazardous chemicals, unlike conventional fluorescent and filament bulbs that contain Mercury, PCB’s and other contaminants. We offer a full recycling program for the bulbs we replace with any retrofit including a certificate of recycling. Let us take all of your fixtures back to our recycling center and dismantle and recycle them safely, properly and friendly to the environment. Help mother earth while lowering your power consumption and saving money.

Biggest Savings

The biggest savings come from replacing high intensity / high wattage fixtures such as Mercury Vapor and Metal Halide that burn long hours. These fixtures are in warehouses, parking lots, and on the sides of buildings (wall packs). The benefit of steady, pure, white light will improve employee productivity and attitudes to add even more to your bottom line.
